IPC: G06F13/00
Filed: 1984-05-08
Abstract: PURPOSE:To improve the processing speed by preventing duplication of complicated processings such as saving of registers, etc. accompanied with the interrupt processing. CONSTITUTION:When an interruption of a level iRQ is generated, a processor of a communication controller checks contents of a mask after the executing instruction is terminated. If the mask is turned ON, a program executed at present is executed continuously because the program has the level iRQ. If the mask is turned OFF, contents of a program counter and internal registers which are used till then are saved in a specific area of a memory, and the mask is turned ON for the purpose of evading the interruption of another program, and thereafter, contents of the program counter are replaced by a jump instruction to start the interruption processing of the level iRQ.

Abstract: PURPOSE:To relieve a user of design burden and reduce the number of pins of a package by a method wherein a test signal from a test signal generator is switched to a signal to a basic block by an external control signal and inputted to the basic block. CONSTITUTION:A D/A converter block 13 is composed of a counter circuit 8 which generates a test signal of a D/A converter 3 and a selector circuit 2 which switches the test signal from the circuit 8 to a signal inputted from an I/O terminal 6 through a user circuit 1 and transmits the signal to the converter 3. If a control terminal 9 is set at a required state so as to have the block 13 in a test mode, the circuit a is reset simultaneously and all the outputs of the circuit 8 become '0'. In this state, a zero scale error is measured. Then a clock is inputted to a clock input terminal 10 and a full scale error and a linearity error are detected. With this constitution, the number of terminals can be reduced and design burden of test circuit insertion can be eliminated.

IPC: H01L21/316
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To flatten the surface of a substrate, lower manufacturing temperature therefor, and reduce its manufacturing cost by using both disilane and tetraethoxysilane as a main material, and manufacturing a silicon oxide film at a specified mixing ratio by CVD. SOLUTION: An silicon oxide film is manufactured by CVD using both disilane and tetraethoxysilane as a main material. It is preferable that the mixing ratio of disilane to tetraethoxysilane is 0.01-0.1mol to 1mol. In addition to the main material composed of disilane and tetraethoxysilane, one or more kinds of boric ester, phosphoric ester or phosphite are used as accessory materials. A silicon oxide film containing one or more kinds of boron oxide or phosphorus oxide therein is thereby manufactured. This enables the formation of minute insulating films at low film formation temperature, and makes the surface of substrates excellent in flatness.

Filed: 1995-03-27
Abstract: PURPOSE: To simplify excavation preparation work by installing a rotary cutter head to a frame with an out rigger and mounting removably a propulsion jack thereon and fixing the frame at a specified position and then excavating a vertical hole. CONSTITUTION: A frame 14 of a vertical hole excavating device 10 is fixed at a specified position and held horizontally with an outrigger 24. An excavation cutter 68 which comprises a ring-shaped first head 64 and a second head 66 is turned by a drive device 54, thereby excavating. In this case, a removable propulsion jack 20 propels, taking up a reaction force with a reactor mounted on the frame 4. The excavated earth and sand is collected in the second header 66 with this excavation. The whole head 66 is lifted up so that the earth and sand therein is loaded on a truck or the like and discharged. The holes thus excavated are lined one after another. The propulsion jack 20 is mounted on the lining and propels while taking a reaction force with the lining.  This construction makes it possible to simplify a preparation work prior to excavation and excavate a larger-sized hole with higher efficiency.

Abstract: PURPOSE:To generate the inspection plate which has excellent color separation characteristics and high definition by making parallel light incident on an interference filter. CONSTITUTION:A convex lens 92 as a 1st optical member is arranged between an electrodeless light source 44 and a turret 50 and the divergent light from the electroless light source 44 is converted into the parallel light. Namely, the light is made incident on the interference filter 56 fitted to the turret 50 perpendicularly to this interference filter 56 to remove variation in the transmission characteristics of the interference filter when the incident light is made incident on the interference filter. Consequently, the inspection plate which is free from color mixture and has good color separation characteristics is obtained. Further, a concave lens 92 as a 2nd optical member converts the light passed through the filter 56 into a divergent light again to expose the entire surface of a document film 32. Further, the film is exposed to the parallel light by using a Fresnel lens to obtain the inspection plate which has the high definition and eliminates misestimation.

Title: New peptide, inhibitor of gastric acid secretion-antiulcer agent and food and drink comprising the same peptide as active ingredient
IPC: A23L21/10
Filed: 1992-03-18
Abstract: PURPOSE:To obtain an economically advantageous new peptide, having a specific amino acid sequence, capable of exhibiting inhibiting action on gastric acid secretion without any side effect, useful as an inhibitor of the gastric acid secretion, an antiulcer agent or a food and drink for preventing ulcer and derived from a mammalian milk or its processed product. CONSTITUTION:A whey concentrate is dissolved in water at 50 deg.C and regulated to pH 7.3. The regulated solution is then subjected to ultrafiltration through an ultrafiltration membrane having 20000 fractionation molecular weight. The resultant permeation liquid is then regulated to pH 7.0 and resubjected to ultrafiltration under the same conditions, desalted and concentrated. Water is subsequently added to dilute the concentrate. Thereby, diafiltration is carried out and the diluted concentrate is then concentrated and freeze-dried to provide a kappa-casein glycomacropeptide (GMP) crude fraction. The obtained fraction is subsequently passed through an anion exchange resin column and eluted with a 20mM tris-phosphoric acid buffer solution (pH 8.7) containing 0.3M common salt. The obtained eluted fraction is purified by a reversed phase high-performance liquid chromatography to afford the objective new peptide having an amino acid sequence expressed by the formula [(P) is phosphate group] and inhibiting action on gastric acid secretion.

Title: Holding tool for holding writing tool between tip of index finger and second joint

IPC: G06F3/03
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To obtain a holding tool which makes a person learn how to write naturally and how to hold correctly. SOLUTION: A conventional writing tool is shortened to a length from a paper face to the second joint 4 of the index finger and a ring type and feather type holding tool 1 is fitted thereon. For fitting the holding tool 1 on the writing tool 2, the writing tool is made removable or a disposable type prepd. by integrating the writing tool 2 and the holding tool 1 in a body is provided. Writing is performed by holding the writing tool 2 between the tip part 3 of the index finger and the second joint 4. In the conventional writing tools 2, a bad habit to grasp firmly is easy to get by all means caused by its length and hardness. However, when the writing tool 2 is shortened, grasping firmly it is hardly performed and a correct way to hold is naturally made a habit. Originally, letters and drawings are written by the index finger.  However, as the conventional writing tools 2 are long, they do not direct the same direction as the direction of the index finger. The reason why the conventional writing tools 2 are difficult to write or use exists in this point. As the writing tool 2 is held on the index finger by means of the holding tool, the direction of the writing tool 2 becomes the same direction as that of the index finger and it is epoch-making as natural way to write and easiness to use are enough obtd.
